Writing an SMTP service in Go

Because sometimes, it's nicer to users to allow them to contact us by email, it occasionally becomes useful to handle incoming mail. Let's see how.

In this talk I have at DevoxxFR 2023 on 2023-04-14, we shall see

• the pros and cons of push (straight SMTP with or without TLS) vs pull (POP3, IMAP4, CDO, MAPI...) strategies to handle incoming mail
• how to choose between full custom code and the cloud solutions provided by AWS SES and GCP GAE inbound email handling
• a concrete example of how to write a SMTP server pretty much like one would write a classic HTTP server in Go 1.20
